The ANTI-GOD CULT of scientology will threaten any person with total exposure of all their confessed sins and secrets, if you dare leave, EXPOSE or confront them. That is the weapon that controls ALL CELEBRITIES, PROFESSIONALS AND COWARDS. The weak have given up their soul and now find that their confessions of their own sins and deep dark secrets -- will be made public knowledge. Hayes would not, could not, leave Scientology over South Park. So he did the opposite.
On March 13, 2006, Hayes gave public notice that he was leaving South Park over the infamous Scientology episode. March 13th just happens to be L. RON HUBBARD'S BIRTHDAY. This isn't just some mild coincidence - his birthday is a major holiday in the cult.
Scientologists believe that we are all immortal Thetans and this is why the Sea Org requires a billion-year contract of service! This is also why an office is kept for Hubbard in every Scientology church - for his invisible Thetan spirit to use whenever he just happens to float into town! Likewise, you will continue to see Isaac Hayes mentioned on cult promotional materials, because as far as they're concerned, Hayes is STILL ALIVE as a THETAN GHOST and still supports the "TRUE GROUP" of Scientology.
He continues to be listed as if he is still alive on Alfreddie Johnson's World Literacy Crusade site.
